I'o all whom t may concern Be it known that- I, GEORG a citizen of the Republic of Saxony, Grer-` many, residing at Dresden, Germany, have invented certain new and useful improvements in a Disk` Spooling Machine, of which the .following isa specification.

Saool winding devices particularly for` wind with the thread position, this guide surface" may be formed differently from the usual style `of plane surface asa rod or roller, the longitudinal yairis of which is parallel to that of the spool. y

It is also alreadyknown to-arrangethe devicel for holding the spool on the one end of a lever which is provided Awith a friction roller, and for the purpose of bringing into gear the spooling device to press this lever with its friction roller againstA the peripheryof the driving wheel so that the friction roller of the lever lwhich roller is mounted on the hollow spindle carrying the spool is thus driven by friction. l/Vhen the spool increases in size with the windings it presses resiliently against the thread regulating surface. This pressure has already been used to disconnect the meansv which press the spool carrier against the driving mechanism. Itis thus already known to utilize theincrease in sizey of the spool after the desired amount has been wound on to disconnect the spool carrier fromthe drive by the pressure of the guiding surface.

The disk spool machine yforming the sub- ,..Ajeet ofthe present invention` operates on these principles. Itl is, however, characterized by this that the spool carrier .is pressed resiliently against the driving mechanism, and in opposition 'to this spring.

action the .thread f regulating surface is pressed under a ysmaller pressure against the spool. Due to theincrease Vin size of the spool the surface is pressed against a fixed` pro] rier from its drive by overcoming the presectionand any further increase I, yfin size onthe Aspool-releases y the spool carp sure of its spring. It has been found that in this manner a very exact winding of the spool `and a `very exact stoppage of the spool drive is attainableat the desired nioment in machineshaving high output,V l

The new. machine is illustrated in `the drawingin which Figl 1 is an end elevation partly in vertical section. Fig. 2 is a side view and 3 a plan. Fig.` e-showsthe thread guide in detail, `and Figi5 shows the Inodev of attachment of the spool..

As shown the thread 1 to beiwound is led over a guide 2 to the spool The spool is fixed in a` spoolcarrier which is'formed,

as a single armed lever rotatable `about theadpisting rod 5. This leverseen from above is of Ll-shapedform.` At the free i ends ofthe arms of this U-shaped member are provided known means for receiving and holding the spool.` Oney end of the spoolis fitted in the hollow head f6 of `a spindle to which is secured the driving roller 7. This drivingroller rests on the periphery` on al drivingwheel 8, a spring 9 engaging a spool carrying lever 1 server ing to pressthe friction roller down ofthe periphery of the driving wheel 8f Thek other end ofthe spool is fitted in a head 10 the' spindle of which is resiliently pressed forwards, whereby the spool held between the twoheads 6 and 10 and is rotated therewith.

y In order to regulate the position of the thread there is provided a roller 11. This roller is carried by a double-armed lever 12 which is formed as a rectangular frame, and swings ony bolts 13 carried by `the frame. On the fre-e end/of this double-armed lever 12 engages a tension spring 14 having"sul stantially thes'aine direction as thespring 9 acting on the leverl. i p This spring pullsvdown the rear end of the frame 12 and the front end thereof pushes up the `roller 11 against the spool vcontact between these two members takingA `placealong a line parallel to the longitudinal axis of the spool. y

The roller "11 causes wound to be wound in uni/form adjacent coils onthe spool. The lever 12 is providedat its rear `free end witha downwardlypro, jecting pin 15 which maybear. on the adjusting plate 16. This has for its obiect to revent unnecessary movement of the lever 12 when the lever Z1 is raised say by a handle say are arresti` `being 17. In such case if the means for preventing swinging` of the lever be absent, it would rise unnecessarily following the spring'lk At the end opposite the spring 14 the lever 12 is provided with an adjusting screw 15', the axis of which liesingthel plai'ie" of` j movement of the lever. Thel downwardly projecting end of the adjusting screw ei;- tends'towards the adjusting plate 16. j

The relative tensions of the springs 9 and 14,., are so arrangedl that the spool carrying lever 4 is pulled downwards' with a greater force than` that withlwhich the end of the double-armed lever 12 carrying the roller 11 is pressedupwardsbyfthespring 14. lhen the thread 1 iswound on'the spool 3 vand the thickness `of'winding is increased bysuccessive layer-sof thread the roller 11 and `also the lever 12 overconiingtlie tension ofthe spring 14- is moved by the amount of in` creas'e'lin the'coils'untilthe lower end of .thev adjustingscrewvl bearsV on the plate 16.

,The adjustingscrew allows regulation as desired of the thickness' ofthe spool'. .As

i, sooiifasV the adjusting screw contacts with the' plate 16 the lever 12becomes rigid and further movement cannot taire place. Fur.- ther additional ceiling ofthe spool then causes the lever't overcoming the tension of,

the.l spring 9 to be raised. The raisingmo'vement effectsA as a direct consequence the liftingofthe roller 7 of the spool spindle running'on'the drivingwhee'l 8. p

At the moment whenthe roller 7 is. raised i from the driving'wheel 8, the d'riverof the spool spindle' ceases. It is stopped landI the f winding ofthe spool is thusautomatically stopped at the desired point.

The thread 1 is led over the curved guide or strap 2.

As the thread passes from a fixed eye, the

distance fr'omone eye to the spool alters continuously, the distance being greatest when the thread is at oner end of the spooll` 4 andleast `when the thread is ati the middle of the spool.

The curvature of theguide 2 serves io counteract this effect since it imparts' a greater tension to the thread as it runs over the upper `central portion when being led to the middle of the spool thanwhen the thread is guided' towards oneN end thereof. Consequently the thread retains always the same tension when the guide 2 is properly curved. This formation of the thread guiding 'surface ensures a'uniform thread tefnsion and a uniformly tight winding of the spool the curvature ofthe strap regulating or effecting proper guiding of the thread.

Itis not ,suiicientthat the spoolr end shouldbe heldby fricti'orrin the hollow' spindle head 6 as was previously usual.
